Fusion-io 2.5-inch, SCSI Express-supporting SSDs plugged into the top two ports in the card pictured above. Poulton says these ports are SFF 8639 ones. The other six ports appear to be SAS ports. A podcast on HP social media guy Calvin Zito’s blog has two HP staffers at Vienna talking about SCSI Express. SCSI Express productisation. Fusion-io revealed today that it made another investment in software defined storage. The company announced that it acquired ID7, the UK-based company behind the open source SCST SCSI Linux target subsystem. Financial terms were not disclosed. Today, more and more workloads are running in virtual machines (VMs), including workloads that require significantly more IO in the guest operating system. In a VM on VMware vSphere, all virtual disks (VMDKs) are attached to the LSI Logical SAS SCSI Adapter in the default configuration.
Fusion.io is best known for its ioDrive PCIe SSD cards.

- Hello All, I am having issues with firmware updates on my Fusion-IO Duo PCIe SSD (HP 320GB SLC/HP Part Numbers 600281-B21 & 600477-001). Here is what I have done: 1. I am running under MS Windows 10 Pro (not Windows Server 2012;), HP io accelerator Ver 3.2.8, HP iosphere Ver 3.9.0, on a.
- Was a computer hardware and software systems company (acquired by SanDisk Corporation in 2014) based in Cottonwood Heights, Utah, that designed and manufactured products using flash memory technology. The Fusion ioMemory was marketed for applications such as databases, virtualization, cloud computing, big data.
Fusion-io has announced that it has acquired the UK-based storage technology company ID7, the leading developer of the open source SCSI Target Subsystem (SCST) for Linux. Fusion-io specialises in acceleration technology including high performance and capacity PCIe SSD cards and is also known for employing Steve Wozniak as Chief Scientist. It supplies companies such as Facebook, Apple and HP with its cache technology, though it did note in its 2012 Annual Report that its top ten customers were responsible for 91% of its $359 million revenue and is therefore working to widen its customer base.
ID7, which was founded in 2006, has been collaborating with Fusion-io on development of its ION Data Accelerator software which can cache in conjunction with Fusion-io's PCIe SSD cards. These are typically used with NetApp's Flash Accel, but the ID7 acquisition should allow Fusion-io to expand its software defined storage offerings based around ION Data Accelerator.
Fusion-io says it will 'continue to support the open philosophies that have made ID7 and SCST successful', maintaining an open source version of SCST and continuing to contribute to it. Vlad Bolkhovitin, Founder and Primary Developer of the SCST SCSI Target Subsystem for Linux, said that “By joining the Fusion-io team, we are pleased to be able to provide SCST with more engineering resources and talent to support the development of the open source and commercial SCST subsystems'.

After knocking SSDs for poor performance, Fusion-io is now building one itself – but throwing out existing speed-limiting SSD interfaces designed for disk drives.
A preview device, running at 95,000-plus IOPS, was shown at HP's Discover event in Vienna last month.
Fusion-io has criticised SSDs for poor performance, saying:
The power of SSDs is compromised when compared to memory acceleration options designed as a memory tier, such as PCIe-based flash memory cards. We are finding that PCIe solutions outperform SSDs by a wide margin
Producing its own SSD would be quite a turnaround, but this is what it appears to be doing.
Nigel Poulton blogged: 'The concept box on display at Discover is an early prototype, but was an HP ProLiant server with an early Fusion-io 2.5-inch SSD drive connected to the PCIe bus (I know its not really a bus) via an SFF 8639 backplane connector (PCIe 12Gbps 6 lane). However, this is also do-able over PCIe cable implementations.'
Poulton said: 'They told me that the Fusion-io drive was literally only four weeks old.'
He added: 'It was a 2.5-inch hot pluggable drive. On the outside it looks just like any 2.5-inch SAS drive.'
Fusion-io Scsi Device
A Fusion-io spokesperson said: 'The Fusion-io demonstration at HP Discover included a technology preview that integrated ioMemory technology with the emerging SCSI Express standard in an HP ProLiant server. Fusion-io is excited to continue working with others in the industry to evaluate the potential of these technologies.'
Abandoning HDD interface paradigm for SSDs
This is not an SSD as we currently know it, a device with an interface designed basically for hard disk drives (HDDs).

Grant Jacobson, Fusion-io's director for HP alliances, wrote in his blog: 'Connecting via the PCIe-based SCSI Express standard is consistent with Fusion’s cut-through architecture, which reduces latency and increases performance by moving data closer to the server CPU.
'Our HP Discover 2011 demo uses the same ioMemory and VSL technology as the recently announced Fusion ioDrive2 products, demonstrating the possibility of extending Fusion’s Virtual Storage Layer (VSL) software capabilities to a new form factor to enable accelerated application performance and enterprise-class reliability. '
VSL 'allows file systems, volume managers, and applications to access flash through a common block interface. Similar to page tables in the host virtual memory subsystem, the VSL virtualises flash via 'block tables' and translates block requests to physical ioMemory addresses.'
Host systems could use a Fusion-io PCIe flash card (ioDrive) or a Fusion-io SSD in exactly the same way: as a tier of host system memory underneath DRAM, and not as a faster chunk of external storage accessed through an interface designed to an HDD access paradigm.
